Fusing Consumer Fireworks Cakes
Cakes (also called repeaters or multi-shots) are the backbone of consumer fireworks displays. Learning to fuse them properly creates seamless, professional-looking shows.
Legal Note
Consumer cakes come in 200g and 500g sizes. Never exceed the legal limit in your area. Always check local regulations before fusing fireworks.
Materials Needed
- Visco fuse (green, yellow, or red)
- Aluminum tape or masking tape
- Sharp scissors or fuse cutters
- Nail or awl for poking fuse holes
- Lighter or torch
- Safety equipment
Step-by-Step Instructions
Step 1: Prepare Your Cakes
- Remove any plastic wrap but keep the top paper intact
- Identify the main fuse location (usually on the side)
- Arrange cakes in your desired firing order
- Ensure stable placement on flat ground
Step 2: Plan Your Sequence
- Consider cake duration (usually printed on the label)
- Decide on overlap or sequential firing
- Account for different effect heights
- Mix colors and effects for variety
Step 3: Connect the Fuses
- Cut connecting fuse to calculated length
- For direct connection: tape fuse directly to cake's main fuse
- For delayed connection: add appropriate fuse length
- Ensure at least 1 inch of overlap for reliable ignition
Step 4: Secure Everything
- Use aluminum tape for best results (heat-resistant)
- Tape down all fuse connections thoroughly
- Create a fuse leader for safe ignition
- Double-check all connections
Advanced Techniques
Poked Fusing
For instant ignition, poke a hole in the side of the cake near the first tube.
- Use nail to make hole above first tube
- Insert fuse directly into cake
- Tape securely around entry point
- Creates zero-delay ignition
Chain Fusing
Connect multiple cakes in sequence for continuous action.
- Start with fastest-burning fuse
- Connect cake to cake directly
- Add delays only where needed
- Test timing with single cakes first
Common Cake Types and Effects
| Cake Type | Duration | Best For |
|---|---|---|
| 200g (25 shots) | 20-30 seconds | Quick pace, filling gaps |
| 500g (9 shots) | 15-20 seconds | Big breaks, loud effects |
| 500g (25+ shots) | 30-45 seconds | Long duration, varied effects |
| Fan cakes | 20-30 seconds | Wide sky coverage |
Safety Tips
- Never stand directly over cakes when fusing
- Keep cakes at least 20 feet from spectators
- Secure lightweight cakes to prevent tipping
- Have water or sand nearby for emergencies
- Never attempt to relight a cake that didn't fire completely
